The Health Secretary today warned it will be a “quieter week” for the vaccination programme. But pharmaceutical giants Pfizer and AstraZeneca have said there are no issues with deliveries.
Pfizer sources told MailOnline there were “no supply challenges”.
Meanwhile, AstraZeneca yesterday said it was still “on track” with orders despite “fluctuations” in supply at plants.
Speaking to LBC this morning, Mr Hancock said a drop in the number of coronavirus vaccines being administered would continue all week due to supply issues.
He said: “We have got a quieter week this week and then we’re going to have some really bumper weeks in March.”
The Health Secretary added that had been “ups and downs” in deliveries.
Downing Street today insisted it remained confident in vaccine supplies despite falling numbers of doses being administered in recent days.
The Prime Minister’s official spokesman said: “We continue to ensure that hundreds of thousands of people each day receive the vaccines.
“As we said from the start, there will be daily fluctuations in the number of people who receive it day-on-day but you are aware of our target to vaccinate all those within the first phase by mid-April and we are confident in our supply to be able to do that.”

“It’s the right thing to do.
“I want to obviously offer the vaccine to all adults by the end of July, that’s the target that we think that we can meet, and all over-50s by April 15, and we have been able to bring that forward.
“But we are also, alongside that, working incredibly hard to encourage people to take it if they are unsure.”
